And despite the dainty profile, there is nothing delicate about it. On the contrary, the all-metal exterior offers waterproof, dustproof, and crushproof protection.

Furthermore, its rubber feet prevent the SSD from slipping and keeps your desk scratch-free. So, whether it sits at your desk at home/office or travels with you across seven seas, the Envoy Pro Elektron is well-suited for all occasions.

As for storage, there is no compromise there as well. Let me put that in perspective by illustrating some examples. My 1TB drive can hold up to:

  • 4.3 million MS Office documents
  • 200,000 photos
  • 200 high-definition movies
  • 41.6 hours of GoPro 4K footage
  • 24+ PS4/Xbox games

OWC Envoy Pro Elektron USB-C SSD: Hardware and performance

OWC packs some of the best technologies currently available. Thanks to the Asmedia ASM-2362 controller and NVMe M.2 interface, Envoy Pro Elektron is roughly twice as fast as compared to previous generations of SSDs.

As per OWC, if all systems are a go, the drive can offer up to 1011MB/s sequential read/write performance. However, it fell a little short on the claim and averaged around 930MB/s read/write speed in our tests.
